package FA11B00 is -- Application_One_Widget
-- This foundation simulates code that might be obtained as an already
-- implemented set of objects and services, perhaps from a source code
-- vendor. It represents processing of widgets in a window system.
-- These widgets all have the same characteristics, but they are application
-- specific, so we do not allow assignment of an App_1_Widget to App_2_Widget.
-- The dimension measurement is in pixels (dots on the screen).
